About 123 ToDo
The free, privacy-first task manager and voice note engine built for people who demand simplicity, zero data lock-in, and 100% zero-knowledge encryption over their data.

Our Story
Why We Built 123 ToDo
In a digital landscape where mainstream productivity apps track your activity, store unencrypted task data on commercial cloud servers, and charge aggressive monthly subscription fees, we asked a fundamental question: Why can't task management be fast, private, and free?
123 ToDo was engineered to eliminate software fatigue. We stripped away database configuration bloat, subscription paywalls, and intrusive tracking scripts to build an application grounded in core principles:
- ✓ ⚡ Fast & Offline-First: Powered by Progressive Web App (PWA) technology, launching in milliseconds with 100% offline capability.
- ✓ 🛡️ 100% Zero-Knowledge Encryption: Your tasks and notes are encrypted client-side using AES-256-GCM before leaving your device.
- ✓ 🎙️ Dual Skin Versatility: Seamless 1-tap toggle between structured Task Management and high-contrast Simple Voice Notes dictation.
- ✓ 🎁 100% Free Forever: No premium tiers, no hidden paywalls, no feature restrictions.
Field & Desk Versatility
Dual Skins & Hands-Free AI Voice Dictation
Whether you are working at a desk or inspecting a job site in the field, 123 ToDo adapts to your environment through our **Dual Skin Operating System**:
📋 Task Manager Mode
Features our structured P1–P4 priority matrix (Must Do, Should Do, Could Do, On Hold), custom color-coded project streams, drag-and-drop reordering, subtask checklists, and strategic due dates.
🎙️ Simple Voice Notes Mode
High-contrast, large-text dictation interface designed for trade contractors, builders, and field work. Tap the red Talk button for continuous dictation with spoken punctuation, live voice editing commands ("scratch that", "delete last word"), and hands-free submission directly into an Unassigned Inbox.
Privacy & Cloud Sync
Zero-Knowledge Security & E2EE Cloud Sync
We believe privacy is a fundamental human right. Unlike cloud services that store plaintext tasks on corporate servers, 123 ToDo encrypts all your data on your local device using **AES-256-GCM client-side encryption**. Neither 123 ToDo, Cloudflare, Google, nor third parties can read your task titles or notes.
Dual Encrypted Sync Options:
- ⚡ 123ToDo Cloud Sync (Default): Powered by Cloudflare D1 serverless edge database with 5-second 6-digit device pairing codes. Eliminates 1-hour session expiration drops and WebKit PWA storage wipes on iOS devices.
- 📁 Google Drive AppData Sync: Syncs encrypted payloads directly to your personal Google account's hidden AppData folder.
